Title: Process for the regeneration of the adsorption capacity of activated carbon containing impurities of sulphuric acid and sulphur
IPC: C01B31/08
Filed: 1948-09-20
Abstract: In regenerating activated adsorptive carbon containing sulphuric acid and sulphur impurities particularly carbon used to recover carbon disulphide in the viscose process, by washing with dilute solutions of alkali metal carbonates or bicarbonates, e.g. NaHCO3 or Na2CO3, only excess liquid is discharged after the washing and the carbon without re-washing with water, is dried, say at 110 DEG  C., with adhering alkaline solution.  The carbon should be water washed first and is preferably treated in two stages first with say 4-5 per cent NaHCO3 solution and then with say 6-10 per cent NaHCO3 solution. Specification 264,854, [Class 90], is referred to.

Title: Improvements relating to dynamo electric machines for converting alternating electric currents to direct electric currents or vice versa
IPC: H02K47/02
Filed: 1932-09-12
Abstract: 406,759. Rotary converters. PESTARINI, G. M., 4, Tapton House Road, Sheffield. Sept. 12, 1932, No. 25387. Convention date, Sept. 12, 1931. [Class 35.] In a machine in which variable voltage continuous-current is collected from or supplied to a set of brushes on the armature according to whether alternating-current is supplied to or obtained from the armature, and adjustable continuous-current at constant voltage is supplied to another set of commutator brushes, the stator has windings arranged to produce flux in the same direction as that of flux which would be produced by the constant voltage current fed to the armature, and the fluxes produced by the continuous armature currents are substantially uncompensated. As shown, windings 8-11 cause the poles 4, 5 to have the same polarity, and opposite to that of poles 6 and 7 whereas windings 12-15 give the poles 4, 7 also 5, 6 the same polarity, but windings 9, 10 and 14, 15 may be omitted. The constant voltage current fed to brushes a, c may be obtained from a direct-coupled exciter. When alternating-current is fed into the slip-rings 2, which may be connected to the common armature winding or to a separate winding, the current obtained from brushes b d may be constant or may vary in proportion to the load, and adjustment is obtained by means of the stator windings and/or the voltage at brushes a, c. The stator may also have damping windings to avoid hunting and these may also serve to enable the machine to be started as an induction motor. Specification 24137 /09, [Class 35], is referred to.

Abstract: 1,016,700. Feeding sheets. RANK-XEROX Ltd. July 3, 1962 [July 3, 1961], No. 25437/62. Heading B6B. [Also in Divisions F2 and G2] A xerographic printing- machine includes separator means and feeding rollers driven alternately through a clutch, a sheet being separated from a stack and momentarily stopped in abutment with the stationary feed rollers whereby the sheet is buckled to ensure alignment of the leading edge of the sheet with the feed rollers and then the feed rollers operated to feed the sheet to a rotating xerographic drum. Friction separator rollers 451 are mounted on a shaft 452 through a slip clutch 462. The shaft 452 is carried by a housing 454. The separator rollers 451 are driven from a rotatable shaft 455 by means of pulleys 461, 463 and an endless belt 464. The shaft 455 is spring-biased to the left, as seen in Fig. 6, to engage a drive pin 473 on one end of a shaft SH-11. A pulley 476 secured to the shaft SH-11 is operatively connected to clutch element S 11 loosely mounted on a constantly rotating shaft SH-7, Fig. 9. The feed rollers 401 are operatively connected to clutch element 512 also loosely mounted on the shaft SH-7. An armature 514 is keyed to the shaft SH-7 so as to rotate therewith but capable of axial movement between the clutch elements 511, 512. The armature, which is normally de-energized, is biased into driving engagement with clutch element 512 by means of a spring 518. The armature is periodically energized to move it into driving engagement with the clutch element 511 to drive the separator rollers. The pressure of the separator rollers 451 on the stack is adjustable by rotating a gear wheel 485. The latter is secured to a sleeve 484 loosely mounted on the shaft SH-11. The sleeve is connected to a bearing 475 in which the shaft SH-11 rotates, by a coil spring 488. Said bearing 475 is connected by teeth 482 to a sleeve 481 fast with the housing 454, Fig. 6. A cam 494 fixed to the bearing 475 is rocked by a roller 495 on the paper supply tray, Fig. 4, whereby the rollers 451 are lifted clear of the paper stack when the paper supply tray is moved into or out of its operative position.

Title: Improvements in plucking machines for poultry and the like

Filed: 1935-09-13
Abstract: 461,572. Plucking poultry. MELMORE, W. M., and MELMORE, A. L. Sept. 13, 1935, No. 25452. [Class 28 (ii)] A poultry-plucking machine comprises rotary discs 2, 2a, the discs 2 being fixed on the rotary shaft 3, during the plucking, whilst the inter. posed discs 2a rotate with the shaft and are, at the same time, rocked from side to side so that the peripheries of the fixed and rocking discs come together to grip feathers protruding through the plucking aperture of the casing 1. The discs 2 are spaced by and held between members 12 on which the discs 2<a> are loosely mounted, each disc 2<a> being acted upon by a push-rod 9, slidable in a member 15 rotating with the shaft 3, and having a head which contacts with a stationary cam surface 10 whereby the rods 9 are moved against the action of returning-springs 14. The discs 2a are provided with fulcrums in the form of protuberances 11, or balls set in the discs, which bear against the fixed discs 2 in such manner that the actions of the rods 9 bring the peripheries of the discs 2<a> against the discs 2 at the plucking opening. Springs 13 positioned between the discs, effect the return of the discs 2<a>. To facilitate cleaning of the discs 2, 2a, a threaded block 25 is unscrewed by a handle 26 until the pieces 12 are released from the clamping pressure, the rocking of the discs 2<a> then ceasing. Inward screwing of the block 25 compensates for wear on the push-rods. The upper edge of the plucking opening is provided with a blunt chisel-shaped member which causes the stub feathers to stick outwards when the bird is drawn across the opening. Several such plucking-heads may be arranged in one machine, the outlets of the casings 1 being connected to a suction fan which delivers the feathers to a T-piece, a featherreceiving bag being arranged to hang from one limb of the T-piece whilst an air-exhausting bag is suspended with its mouth downwards and secured to the aligned limb of the T-piece. The bags are held on the T-piece by coiled springs, and the suction pipe of the fan is fitted with an inwardly-opening spring-loaded safety valve.
